In technical drafting (AutoCAD or similar), if two extension lines accidentally cross and create visual clutter at the intersection, what practical editing command should the drafter apply to clean up the crossing and improve readability?

Introduction / Context:
Clear, unambiguous dimensioning is essential in engineering drawings. When extension lines cross, the drawing can look messy and may cause misinterpretation on the shop floor. Most CAD platforms provide editing tools that let you remove or interrupt parts of lines at the crossing so the intent is obvious.

Given Data / Assumptions:

• The condition is a visible crossing of two extension lines near a dimensioned feature.
• The goal is to improve legibility without changing the actual dimension values.
• Standard CAD editing tools (Move, Stretch, Break, Trim, etc.) are available.

Concept / Approach:
Instead of redrawing the entire dimension or moving geometry, the fastest fix is to introduce a gap at the overlap point. A break creates a small, intentional space that visually separates lines, eliminating the confusing junction while preserving all geometry and numeric annotation.

Step-by-Step Solution:

Verification / Alternative check:
Compare before and after prints or PDFs. The broken gap should make the extension lines visually distinct, reducing the risk of misreading while maintaining dimension integrity.

Why Other Options Are Wrong:

• Use the Modify tool to clean up the extension lines.: Too vague; Modify is a menu category, not the precise fix.
• Use the Tolerance tool to clean up the extension lines.: Tolerance settings relate to permissible variation, not line cleanup.
• Use the stretch tool to clean up the extension lines.: Stretch moves endpoints and may distort alignment or associativity.

Common Pitfalls:
Breaking too large a segment or breaking the dimension line instead of the extension line can reduce clarity. Keep the gap small and located at the crossing only.

Final Answer:
Use the Break tool to clean up the extension lines.
